-Letters Patent No. ,96,966, dated November 16, 1869.

IMPROVED WRITING-DESK The Schedle referred to in these Letters Patent and making parte! the same.

To all whom it may concern:

Be it known that 1, FREDERICK ItoBBIN, of HudsonCity, in the county of Hudson, and State of New J exsey, have invented a new and useful Improvement in Convertible Writing-Desks; and I do hereby declare that` the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference beingr had to the accompanying drawing, forming part of this specification.

'lhis invention relates to a new and useful improvement in writing-desks, whereby they are made much lllOl'e useful than desks of ordinary construction, and consists in so constructing and arranging the top and the case containing the drawers and pigeon-holes that a writing-desk or a table may he thrilled at will, as will be hereinafter more fully described.

1n the accompanying drawings- Figure l represents a vertical section, showing the parts arranged as a'table, with the case dropped beneath the top.

Figure 2 is a vertical section, showing the parts arranged as a desk.

Similar letters of reference indicate corresponding parts.

A is the top, and

fB is the case containing the drawers and pigeonf holes.

C represents the frame or body, to which legs may be attached.

D represents slotted'curved plates attached to the top on each side.

E is a sector-plate pivoted to each side ofthe frame C, on which the bottom of case B rests.

1t is by moving this sector-plate back and forth on its pivot that thevcase is raised, as seen in tig. 2.

F is a rod, which connects the sector-plate E with the slotted plate D.

As the top A' is drawn out or forward,the wrist-pinv G, by which the rod is attached to the` slotted plate- D, slides in the slot and draws up the sectorf plates and raises the case.

H represents a support for the top, (on each side,) which is pivoted to the frame at I, and connected with the sector-plate at I', so that when that plate is raised,

To convert the desk into a table, the top is drawn back from the hooks K, and raised while it is pressed back, so as to force back the plates E.

As the plates E turn back, the case follows until it drops entirely1 within the frame, as seen in iig. 1.

The top A then assumes 'a horizontal position, and atahle-is produced suitable for all ordinary purposes.

When the top A is in the inclined position, it may he drawn from the hook K Aand raised snt'ciently to give access to the compartment beneath it.

On the hack of the trame there are hooks, L, with which the lhack ofthe top engages, as it does with the hooks K.

This arrangement keeps the topA secure when locked and in the table form. Having thus described my invention,

I *laim as new, and desire to secure by Letters Patent- 1.' The arrangement of the top A and case B, in con'|.hination with the frame C, whereby the desk or the table isv formed, as described.

2. In combination with the convertible' desk, the sector-plates E, whereby the case B is raised, as described. 3. The supports H, in combination with the rods F and plates E, as and for the purposes set forth.

.4. The combination ot' the plates E, rods F, slotted plates D, case B, and top A, arranged and operating as described, for the purposesspecified.

The above specification of my invention signed by" me, this 6th dayvof October, 1869. Witnesses: FREDERICK ROBBIN. GEO. W. MABEE, `ALEx F. ROBERTS.
